EMI seal for system chassis

Abstract

A method and apparatus for providing an EMI seal in a system chassis. The EMI seal is provided by a bezel assembly for a storage medium drive. The bezel assembly includes a front bezel having an aperture through which a tray can extend for loading and unloading of the storage medium drive, and a tray bezel attached to the tray. Attached to the front bezel is an electrically conductive link. Both the front bezel and the tray bezel include an electrically conductive inner surface. Upon closing the tray, the electrically conductive link provides an electrical connection between the inner surface front bezel and the inner surface of the tray bezel.

     6. The assembly as recited in  claim 1 , wherein the inner surface of each of the front bezel and the tray bezel comprises an adhesive material having an electrically conductive side and an adhesive side in contact with at least one of the front bezel or the tray bezel. 
   
   
     7. The assembly as recited in  claim 1 , wherein the inner surface of the front bezel is electrically coupled to a chassis of an electronic system. 
   
   
     8. The assembly as recited in  claim 7 , wherein the chassis of the electronic system is electrically coupled to an electrical ground. 
   
   
     9. The assembly as recited in  claim 1 , wherein the electrically conductive link comprises a conductive clip attached to the front bezel. 
   
   
     10. The assembly as recited in  claim 9 , wherein a plurality of conducive clips are attached to the front bezel. 
   
   
     11. The assembly as recited in  claim 1 , wherein the electrically conductive link comprises an adhesive material having an adhesive side and an electrically conductive side. 
   
   
     12. The assembly as recited in  claim 1 , wherein the storage medium drive is a compact disk (CD) drive. 
   
   
     13. The assembly as recited in  claim 1 , wherein the storage medium drive is a digital video disk (DVD) drive. 
   
   
     14. A method for providing a closed loop EMI connection in a storage medium drive, the method comprising:
 providing a front bezel having an aperture through which a tray can extend for loading or unloading of the storage medium drive, the front bezel having a first electrically conductive surface;  
 providing an electrically conductive link attached to the front bezel;  
 providing a tray bezel attached to the tray, the tray bezel having a second electrically conductive surface; and  
 closing the tray, wherein when the tray is in a closed position, the conductive link provides an electrical connection between the first electrically conductive surface and the second electrically conductive surface.  
 
   
   
     15. The method as recited in  claim 14 , wherein the electrically conductive material is a metallic coating. 
   
   
     16. The method as recited in  claim 15  further comprising applying the metallic coating by spraying. 
   
   
     17. The method as recited in  claim 15  further comprising applying the metallic coating with a brush. 
   
   
     18. The method as recited in  claim 14  further comprising attaching a first piece of metal to the front bezel to form the first electrically conductive surface and a second piece of metal to the tray bezel to form the second electrically conductive surface. 
   
   
     19. The method as recited in  claim 14  further comprising forming the first and second electrically conductive surface by attaching adhesive material to each of the front bezel and tray bezel, respectively, wherein the adhesive material has an adhesive side and an electrically conductive side. 
   
   
     20. The method as recited in  claim 14  wherein the first electrically conductive surface of the front bezel is electrically coupled to a chassis of an electronic system.
